No. 34802. Here, the molten metal flows from the vessel through a channel-shaped casting nozzle into a swirling cooling bath. The distance between the casting nozzle and the cooling bath is measured in order to solidify the molten metal into strips of uniform thickness. The pressure of the molten metal in the container is set appropriately. Due to this control circuit, fluctuations in the band thickness occur, and the fluctuations must be offset by a smooth roll.

い。Japanese Unexamined Patent Publication No. 63-183747 discloses a method of solidifying the molten metal at the inclined cooling wall of the molten metal container. The wall is subjected to ultrasonic vibrations which prevent the molten metal from sticking to the wall. The solidified molten metal is drawn upward as a band from the wall by the rollers. Since the resulting strip thickness is related to many parameters, it is difficult to obtain a uniform strip thickness. Furthermore, the requirement for clean steel cannot be taken into account due to the open casting in which the molten metal comes into contact with air.

Japanese Patent No. 49 describes a casting method of flowing a molten metal onto a support plate. This support plate is excited by ultrasonic vibrations, and the molten metal that solidifies on the support plate is given a moving direction in the guide direction. This has little effect on the thickness of the strip resulting from the solidifying melt. In this case as well, open casting is performed.

提案することである。The object of the present invention is to propose a method for improving the dimensional accuracy of solidified metal cross sections. Furthermore, this method blocks the air and enables the solidification of the metal. A further object of the invention is to propose a casting device which enables the solidification of the molten metal even in cross sections other than pure rectangles.

Also with respect to the device, according to the invention, the passage is provided with one or more vibration generators for exerting ultrasonic vibrations in the passage in the range of at least 5 kHz, in particular 20 kHz and higher.

分布を保証する。The passage contains molten metal at the transition zone from its molten state to its solid state. The passages, on the one hand, contain the molten metal that is still molten and, on the other hand, the molten metal that has already solidified, and thus define a cross section of the molten metal that is continuously solidified. It is not necessary that the continuous metal slab formed during solidification of the melt fill the entire height of the passage above the melt level. In that case too, uniform dimensions, and in some cases different cross sections, are obtained over the thickness and width of the continuous slab. The high frequency vibrations of the passage ensure, on the one hand, that the solidifying melt does not adhere to the passage walls and, on the other hand, the movement or distribution of the melt in the passage.

る。In a development of the invention, the passages are heated or cooled. Heating the passage prevents premature solidification of the melt. Cooling promotes solidification of the molten metal in the form of a continuous slab solidified shell, in which there is still a molten core in the solidified shell. In particular, the metal that enters the passage in the molten state is cooled while continuing to flow in the passage on at least one side until it forms at least a continuous cast solidified shell.

ラミック通路は金属通路より有利である。The passages can be water cooled, as in known continuous casting molds. In this case, it is possible for the passages to be made of metal, especially copper. However, the use of refractory ceramic materials in the passages is advantageous because it allows the selection of materials that are completely or only slightly wetted by the metal to be cast. This promotes the effect of vibration of the passage so as to prevent the solidified melt from adhering to the passage wall. The use of refractory ceramic materials also makes it possible to keep the melt in the passage in the molten state in the heating zone without the formation of shells, which is also advantageous for metallurgical reasons. In the cooling zone following the heating zone, the cooling power allows the molten metal to be cooled appropriately without having to consider the softening temperature of the metal mold. Also in terms of wear, ceramic passages have advantages over metal passages.

れ方向に対して直角に振動成分を作用させるのがよい。In a development of the invention, at least one oscillating component in the flow direction of the continuous metal slab is applied to the passage. Due to this vibration component, the molten metal, particularly in the solidifying stage, is sent away from the container. The vibration component perpendicular to the flow direction of the continuous metal slab prevents the molten metal from adhering to the passage walls. It is preferable to apply the vibration component to all the walls of the passage surrounding the molten metal at right angles to the flow direction.

The withdrawal rate can also be controlled by the positive or negative pressure of the vessel-passage system, which positive or negative pressure acts on the molten metal surface in the vessel. By changing the inclination of the passage, it is possible to superimpose a kind of gravity feed on the feed due to the vibration component. Positive pressure feed or negative pressure feed can be superimposed on the vibration feed.

The level of melt in the vessel 1 and the passage 2 is indicated by S. The passage 2 projects beyond the melt level.

It is closed all around and fitted to the cross section of the strip or thin slab to be cast. However, continuous slabs having a cross section with a thickness smaller than the height H of the passage 2 can also be fed from the passage 2. In particular, in this case, the shielding of the molten metal against the air by the passage 2 connected to the passage 2 and closed all the way to the outlet opening 3 can be further improved, for example, by a sealed argon in the opening area of the passage 2. . In the method performed by the apparatus according to FIG. 1, the solidified molten metal passes upward through the passage 2
Because it is sent from, it is not the original hot spring.

精密制御に役立つ。The method proceeds as follows. In the lower part of the passage 2 there is a metal melt up to the level of the melt S, as in the container 1. The heating device 5 prevents the melt in the passage 2 from undesirably prematurely solidifying and serves for precise control of the melt temperature.

上で更に搬送する際凝固する。The cooling device 6, which extends below the melt level S, is started in order to draw or feed the solidified melt from the passage 2 in the flow direction F. A vibration generator 7 applies a vibration component a parallel to the flow direction F to the passage 2. Due to this high-frequency vibration of the passage 2, the molten metal which solidifies in the form of a strip or a thin slab in the passage 2 is passed from the outlet opening 3 onto the roller 8.
The molten metal that solidifies when it exits the outlet opening 3 is a core B in which the outer shell A of this molten metal has already solidified but has not yet solidified inside.
A solidified shell may be provided so as to surround the. Exit opening 3
Alternatively, the cross section of the passage 2 determines the cross sectional shape of the strip or thin slab to be drawn. If a special cross-sectional shape of the drawn continuous slab is desired, for example corrugated or fin-shaped, the passages 2 have a corresponding cross-sectional profile at least in the region where the melt solidifies. However, on the free surface of the melt in the passage, it is possible to apply suitable vibrations to the melt to give it a contour, for example a wavy fin in the length direction, to solidify in this shape. The core B is a belt or a thin slab that is roller 8
It solidifies during further transport above.

通路２の壁に固着することはない。The vibration generator 7 also adds to the passage 2 a vibration component b (see FIGS. 1 and 2) oriented at right angles to the flow direction F. Thereby, the molten metal can be prevented from adhering to the wall of the passage 2. As a result, the outer shell A of the molten metal that solidifies does not stick to the wall of the passage 2.

Uniformly fill the entire width or cross section of the.

調節することにより制御される。Due to the fact that the outlet opening 3 is above the melt level S, after the container 1 has been filled to the melt level S above it, the above-mentioned withdrawal process is properly started. When the vibration generator 7 and possibly the cooling device 6 are started and optionally the heating device 5 is switched off or the power is reduced, the withdrawal process begins. The withdrawal speed is controlled by adjusting the amplitude and frequency of the vibration component a in relation to the cooling output of the cooling device 6.

ねばならない場合弾性的結合が行われる。The passage 2 is fixedly connected to the container 1 in the region of the inflow opening 4 and detachably from the housing. This bond is generally rigid. If the vibrations applied to the container 1 from the vibration generator 7 have to be dynamically separated from the container 1, an elastic connection is created.

In this case, since the withdrawal speed is possibly controlled by an additional component, it is possible to adjust the angle W. The passage 2 can then be oriented such that it extends horizontally from the container 1 or is inclined downwards.

In this case, the outlet opening can be provided below the inlet opening.

The heating device 5 and the cooling device 6 are not necessary if the outlet opening 3 can be made to emerge in the solidified form in FIG.

The cooling device 6 does not have to extend below the melt level S, as it will start to solidify at the latest.
